The present invention relates to a Hangul input device and method, and more particularly to a Hangul input device and method for efficiently inputting the vowels of Hangul in a portable electronic device, such as a mobile phone.

Today, with the spread of mobile phones and text message services, the frequency of inputting Hangul in mobile phones increases, and thus, users are required to use Hangul keyboard input method to become more familiar with users and to minimize button input for input. In order to meet the needs of users, various methods and input button arrangement methods for inputting Hangul in a mobile phone have been proposed.

Hangul input devices and methods called 'Cheonjiin' are used in cell phones produced by Samsung Electronics. According to the above prior art, a Hangul input device in which a horizontal stroke key (→), a vertical stroke key (↓) and a stroke key (.) For short and long term determination are respectively assigned to numeric keys for inputting Korean vowels. Is used. According to the Hangul input method, input of '한글' is performed by using a combination of buttons '↓' and '·', and input of 'ㅒ' is performed by '↓', '·', It can be performed by pressing the buttons corresponding to '·' and '↓' sequentially four times, and the input of 'ㅙ' is performed by '·', '→', '↓', '·' and '↓', respectively. It can be performed by sequentially pressing the button corresponding to '5 times. However, the Hangul input method of the so-called 'Cheonjiin' method, when inputting the Hangul vowels, has to press a button very many times. For example, in the case of 'ㅙ', you have to press a total of five times to enter a vowel.

As another example of the Korean input device of the mobile communication terminal according to the related art, an input button of the mobile communication terminal includes six consonant buttons, four vowel buttons, and two conversion buttons. The four vowel buttons are located on the number buttons 3, 6, 9 and 0, respectively, and the vowels assigned to the vowel buttons are 'ㅏ', 'ㅗ', 'ㅡ' and 'ㅣ'. The vowels are output when the vowel button is pressed once. When the vowel button is pressed twice within a predetermined timeout, 'ㅓ', 'TT', 'ㅣ' and '-' are respectively output. In addition, the two conversion buttons are assigned to input buttons '*' and '#', respectively, and '*' is used for adding a stroke, and '#' is for converting a predetermined terminal sound into a twin consonant. use. For example, in the conventional Korean input method, in order to input 'ㅕ', the vowel button to which 'ㅏ' is assigned is pressed twice and the "*" conversion button used to add a stroke is pressed once.

However, the Hangul input device according to the prior art also has a large number of strokes and requires a small number of pushes three times in order to enter a simple vowel, and a ㅏㅓ is assigned to enter the ㅔ. Since the vowel button is pressed twice and the vowel button to which 'ㅣ' is assigned must be pressed once, in this case, the button must be entered a total of three times. In addition, the above method assigns 'ㅏ' and 'ㅓ' or 'ㅗ' and 'TT' of the most used vowels to one same input button so that the number of times the button is pressed to input 'ㅓ' and 'TT' is input. Is still a problem, and the problem of Korean input is cumbersome.

In order to solve the problems of the prior art Hangul keyboard input method as described above, the invention of Korean Patent Publication No. 2004-92653 (name of the invention: Hangul input device and Hangul input method using the same) by the inventor of the present application is presented There is a bar. According to the above-described prior art, the user can input with less input frequency for the input of the frequently used vowels, and also assign the related vowels to one button so that the user can easily become familiar with them. .

According to the prior art, 'ㅗ' and 'ㅡ' are assigned to one button (for example, button 9), and 'TT' and 'ㅣ' are assigned to another button (for example, * button). Is assigned. And, when the button 9 is pressed once, 'ㅗ' is input, and when the button 9 is pressed twice, 'ㅡ' is inputted. In the prior art, 'ㅗ' and 'TT' are removed for consistent input of the vowel vowels 'ㅑ', 'ㅕ', 'ㅛ', 'ㅠ' and for the fast input of the double vowels including 'ㅗ' and 'TT'. 1 Hangul vowels are arranged.

However, in Korean input excluding vowel vowels, the usage of 'ㅡ' and 'ㅣ' is more than twice as frequent as 'ㅗ' and 'TT'. The vowel input when pressed) can be used to efficiently input Korean vowels. Accordingly, there is a need for a Hangul input method and apparatus that enables efficient input of Hangul vowels by solving the above problems of the prior art.

The present invention has been made to improve the prior art as described above, and assign 'ㅗ' and 'ㅡ' to one button and 'TT' and 'ㅣ' to another button for efficient input of vowels. After inputting the vowel vowel, 'ㅗ' and 'ㅜ' are read as the first Hangul vowels, and when the other Hangul vowels are entered, 'ㅗ' is read as 'ㅡ' and 'ㅣ' as the first Hangul vowel. An object of the present invention is to provide a Hangul input method and apparatus supporting switching of a first Hangul vowel in a button of '-' and a button of 'TT' and 'ㅣ'.

In addition, the present invention is to arrange the vowel and the consonant buttons so that each Hangul characters have the same correlation, so that the user can input the Hangul characters easily and easily recognized, while using a minimal button for inputting the Hangul vowels. The purpose.

In order to achieve the above object, a Hangul input device according to an embodiment of the present invention, one or more vowel input buttons for inputting the first to third Hangul vowels, for inputting the first to third Hangul consonants Storing the first to third Hangul vowels corresponding to the input of at least one consonant input button and the at least one vowel input button, and the first to the third Hangul consonants corresponding to the input of the at least one consonant input button And a memory means for storing the first Korean vowel stored in the memory means when there is a single input through the vowel input button, and storing the first Korean vowel stored in the memory means. Read and provide a second Hangul vowel and store it in the memory means when there is one input by the consonant input button. Read and provide the first Hangul consonant, and if there are two inputs, read and provide the second Hangul consonant stored in the memory means, and 'ㅗ' and 'ㅡ' are assigned to the first button, 'And' ㅣ 'are assigned to the second button, and'-'and' ㅣ 'are respectively assigned to the first Korean vowel of the first button and the second button when the short vowel is input.

In addition, the Hangul input device according to another embodiment of the present invention, one or more vowel input buttons for inputting the first to third Hangul vowels, one or more consonant input buttons for inputting the first to third Hangul consonants, The first to third Hangul vowels corresponding to an input of a conversion button and the at least one vowel input button for converting a first Hangul vowel to the third Hangul vowel or the first Hangul vowel And a memory means for storing the first to the third Hangul consonants corresponding to the input of the at least one consonant input button, and storing each conversion value corresponding to the input of the conversion button. If there is a one-time input through the vowel input button, the first Korean vowel stored in the memory means is read and provided, and the second vowel is input twice. And reading out and providing the second Hangul vowel stored in the memory means, and reading and providing the first Hangul consonant stored in the memory means when there is a single input using the consonant input button. Read and provide the second Hangul consonant stored in the memory means, 'ㅗ' and 'ㅡ' are assigned to the first button, 'TT' and 'ㅣ' are assigned to the second button, and upon input of a short vowel Is characterized in that '-' and 'ㅣ' are assigned to the first Korean vowel of the first button and the second button, respectively.

In addition, the Hangul input device is 'ㅑ', 'ㅕ', 'ㅛ', 'ㅠ', 'ㅒ', 'ㅖ', 'ㅘ', 'ㅙ', 'ㅚ', 'ㅝ', 'ㅞ' , 'ㅟ', 'ㅢ' and the vowels and compound vowels '입력' and 'TT' is the first Hangul vowel input, except for the vowel input of the other vowels 'ㅡ' and 'ㅣ' And a switching method of the first Hangul vowels.

That is, after the first button or the second button is pressed, it is determined what is the first Korean vowel of the first button or the second button according to the button pressed afterwards. If the vowel button is pressed again when the first button or the second button is pressed once, it corresponds to a vowel vowel, and the first Korean vowel of the first button and the second button is determined as 'ㅗ' and 'TT', respectively. It is to read and provide a double vowels synthesized with the 'ㅗ' and 'TT' and the vowel buttons pressed behind. For example, after pressing the first button and pressing the 'ㅏ' button, the first Korean vowel of the first button is recognized as '로' instead of 'ㅡ' to generate '가'.

Meanwhile, when the consonant button is pressed when the first button or the second button is pressed once, the consonant button corresponds to a short vowel, and the first Korean vowels of the first button and the second button are determined as 'ㅡ' and 'ㅣ', respectively. , To generate the Hangul characters synthesized with the 'ㅡ' and 'ㅣ' and the consonant button pressed behind. At this time, whether the pressed consonant is used as a back letter after the currently inputted vowel or as the first letter of another vowel following it is determined by what button is entered after the consonant button, which is widely adopted in the prior art. In this invention, even if the description is omitted, those skilled in the art can easily grasp. For example, after pressing the first button and pressing the 'ㅂ' button, the first Korean vowel of the first button is recognized as 'ㅡ' instead of 'ㅗ' to generate 'ㅡ'.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention;

As used herein, terms such as input once, input twice, and input three times mean that the same input button is pressed once, twice, or three times within a predetermined time. As will be appreciated by those skilled in the art, pressing the same input button once and then again after the predetermined time, pressing again becomes a new one-time button press, and it is still possible to keep pressing the same button for more than the predetermined time. One button press is continued.

1 is a diagram illustrating an example of arrangement of a Hangul consonant input button, a vowel input button, and a conversion button of a Hangul input device according to the present invention. An arrangement of twelve input buttons will be described with reference to FIG. 1.

As shown, the first input button may be arranged a Hangul consonant 'ㄱ' and 'ㅋ' having a high correlation with the 'ㄱ'. Similarly, input consonants 'n' and 'ㄹ' for Korean input buttons, input consonants 'c' and 'ㅌ' for seven input buttons, and consonants 'ㅂ' and '에는' for input buttons two , The Korean consonants 'ㅅ' and 'ㅁ' for the input button 5, the Korean consonants 'ㅇ' and 'ㅎ' for the 8 input button, and the Korean consonants 'ㅈ' and 'ㅊ' for the 0 input button, respectively Can be placed.

Among the Korean vowels, 'ㅏ' and 'ㅐ', which are considered to be highly related to 'ㅏ', are placed on the input button 3, and similarly, 'ㅓ' and 'ㅔ' are placed on the input button 6, and 'ㅗ' and 'ㅡ' can be placed on the 9th input button, and 'TT' and 'ㅣ' can be placed on the '#' input button respectively. By assigning the related consonants and vowels to one button, users can easily learn the keyboard.

Hangul vowels are the vowels of the beginning and the end of which are pronounced consistently when pronounced according to the nature of the sounds: 'ㅏ', 'ㅓ', 'ㅗ', 'TT', 'ㅡ', 'ㅣ', 'ㅐ', ' 'Short vowels', '등 (') 'and' vowels ',' ㅕ ',' ㅛ ',' ㅠ ',' ㅒ ',' ㅖ ',' '복', 'ㅙ', 'ㅝ', 'ㅞ', 'ㅢ' and the like can be classified into 'double vowels'.

In the present invention, eight short vowels 'ㅏ', 'ㅓ', 'ㅗ', and 'TT' except for 'ㅚ (ㅟ)' which do not combine with other vowels in consideration of the coupling relationship of the vowels as described above. Based on the ',', 'ㅣ', 'ㅐ', and 'ㅔ', all vowels are created using mutual or derivation. Therefore, the present invention assigns the eight short vowels to the four buttons as shown in FIG. 1 and generates all the vowels using the eight vowels, thereby allowing the user to intuitively recognize the Hangul characters input to each input button.

The entire vowel except for eight short vowels ('ㅏ', 'ㅐ', 'ㅓ', 'ㅔ', 'ㅡ', 'ㅗ', 'ㅣ', 'TT') assigned to four vowel buttons in the present invention. 13 are '개' 'ㅑ' 'ㅛ' 'ㅠ', 'ㅒ' 'ㅖ', 'ㅘ' 'ㅙ' 'ㅚ', 'ㅝ' 'ㅞ' 'ㅟ' and 'ㅢ'. Of these, 'ㅚ' and 'ㅟ' are phonologically classified as short vowels, but in the present invention, 'ㅚ' and 'ㅟ' are also classified as complex vowels in their form. Therefore, in the present invention, 13 vowels except the 8 short vowels are referred to as a double vowel and a complex vowel.

Among the Hangul input buttons illustrated in FIG. 1, a '*' button may be provided with a conversion button for performing a conversion to a predetermined vowel or consonant according to a predetermined input combination.

2 is a block diagram illustrating a configuration module of a Hangul input device according to an embodiment of the present invention. As shown in FIG. 2, the Hangul input device includes a Hangul vowel and consonant input button 211, a conversion button 212, a controller 220, and a memory means 230. A device denoted by reference numeral 210 corresponds to a keypad of a mobile communication terminal. The keypad 210 may be composed of a Korean vowel, a consonant input button 211, and a conversion button 212.

Hangul vowel and consonant input button 211 is a button for inputting the vowel or consonant of the Hangul.

The conversion button 212 is a button for converting a predetermined first Hangul vowel classified into a third Hangul vowel or a first Hangul consonant into a third Hangul consonant according to an exemplary embodiment of the present invention. The first Hangul vowels to the third Hangul vowels, the first Hangul consonants to the third Hangul consonants have a morphological or phonetic similarity among a plurality of vowels or consonants in the Hangul input device and the Hangul input method using the same. Means a predetermined vowel or a set of consonants, according to a preferred embodiment of the present invention, the first Hangul vowel is the first Hangul vowel 'ㅏ', 'ㅓ', 'ㅡ' and ' ㅣ ', wherein the second Hangul vowel is' ㅐ ',' ㅔ ',' ㅗ 'and' TT ', and the third Hangul vowel is' ㅑ ',' ㅕ ',' ㅛ 'and' Can include ㅠ '.

In addition, the first Hangul consonant may include 'ㄱ', 'b', 'ㄷ', 'ㅂ', 'ㅅ', 'ㅇ' and 'ㅈ', and the second Hangul consonant may include 'ㅋ', It may include 'ㄹ', '' ',' ㄷ ',' ㅁ ',' ㅎ 'and' ㅊ ', and the third Hangul consonant may include' ㄲ ',' ㄸ ',' ㅃ ',' ㅆ 'and It may include 'ㅉ'.

When the user presses the Hangul vowel and consonant input button 211 or the conversion button 212, the control unit 220 may input an input corresponding to the Hangul vowel, consonant, or conversion corresponding to each input button (hereinafter, referred to as 'Hangul vowel button'). Input, 'Hangul consonant button input, or' Convert button input '. The control unit 220 is maintained in the memory means 230, and reads the Hangul vowel or Hangul consonant corresponding to the received Hangul vowel button input, Hangul consonant button input or conversion button input, read the read Hangul vowel or Hangul It controls the combination of consonants and provides them to the display means 240.

The memory means 230 maintains information about Hangul vowels or Hangul consonants corresponding to vowel input, consonant input, conversion input, or a combination thereof, respectively. More specifically, the memory means 230 stores Hangul vowel or Hangul consonant information according to a combination of pressing the Hangul vowel and the consonant input button 211 and the conversion button 212, and according to the user's input button operation pattern. The Hangul vowel or Hangul consonant corresponding to the predetermined control signal generated by the controller 220 can be read.

The controller 220 reads a predetermined Hangul vowel or Hangul consonant from the memory means 230 in response to an input of the keypad 210 of the user, and provides it to the display means 240.

FIG. 3 is a diagram illustrating an example of a Hangul vowel or a Hangul consonant held by the memory unit 230 and corresponding to each button input.

As shown in FIG. 3, the Hangul corresponding to the first input of the input button 1 is 'ㄱ', the Hangul corresponding to the second input is 'ㅋ', and the Hangul corresponding to the third input may be 'ㄲ'. have. The Hangul corresponding to the first input of the input button 2 may be 'ㅂ', the Hangul corresponding to the second input of the 'ッ' and the Hangul corresponding to the third input may be 'ㅃ'. The Hangul corresponding to the first input of the input button 3 may be 'ㅏ', the Hangul corresponding to the second input may be 'ㅐ', and the Hangul corresponding to the third input may be 'ㅑ'.

The Hangul corresponding to the first input of the input button 4 is 'b', the Hangul corresponding to the two inputs is 'ㄹ', and the Hangul corresponding to the three inputs of the input button 3 may not exist. The Hangul corresponding to the first input of the input button 5 may be 'ㅅ', the Hangul corresponding to the second input may be 'ㅁ', and the Hangul corresponding to the third input may be '.'. The Hangul corresponding to the first input of the input button 6 may be 'ㅓ', the Hangul corresponding to the second input may be 'ㅔ', and the Hangul corresponding to the third input may be 'ㅕ'.

The Korean corresponding to the first input of the input button 7 may be 'ㄷ', the Korean corresponding to the second input may be 'ㅌ', and the Korean corresponding to the third input may be 'ㄸ'. The Hangul corresponding to the first input of the input button 8 is 'ㅇ', the Hangul corresponding to the second input is 'ㅎ', and the Hangul corresponding to the third input of the input button 8 may not exist. The Hangul corresponding to the first input of the input button 9 may be 'ㅡ', the Hangul corresponding to the second input may be 'ㅗ', and the Hangul corresponding to the third input may be 'ㅛ'.

The Hangul corresponding to the first input of the input button 0 may be 'ㅈ', the Hangul corresponding to the second input may be 'ㅊ', and the Hangul corresponding to the third input may be 'ㅉ'. The Hangul corresponding to the first input of the input button # is 'ㅣ', the Hangul corresponding to the second input is 'TT', and the Hangul corresponding to the third input may be 'ㅠ'.

Meanwhile, 'ㄲ', 'ㅃ', 'ㅑ', 'ㅆ,' ㅕ ',' ㄸ ',' ㅛ, 'ㅉ', and 'ㅠ' are respectively described as input buttons 0, 2, Not only can it be input by pressing the 3, 5, 6, 7, 9, 0 and # buttons three times, but each of the input buttons 0, 2, 5, 6, 7 , 9, 0 and # may be input once, and may be input by pressing the conversion button ('*' button in one embodiment of the present invention) once.

A vowel or consonant input by a combination of one input of each input button and one input of a conversion button may be the same as a vowel or consonant input by three inputs of each input button. Accordingly, the user may press the input button 1 three times to input 'ㄲ', or press the input button 1 once and press the convert button once.

In the case of 'ㅏ' or 'ㅓ', pressing the button (button 3 or 6) once inputs the first Korean vowel 'ㅏ' or 'ㅓ', and whether the input vowel is a single vowel or a vowel And the first Hangul vowel does not change according to whether or not it is a complex vowel.

However, in the present invention, in the case of the button 9 to which 'ㅡ' and 'ㅗ' are assigned and the # button to which 'ㅣ' and 'TT' are assigned, whether or not the input vowel is a single vowel or a double vowel and a complex vowel Accordingly, the first Hangul vowel is changed. That is, when the input vowel is a short vowel, 'ㅡ' or 'ㅣ' becomes the first Korean vowel, and when the input vowel is a double vowel and a compound vowel, the 'ㅗ' or 'TT' indicates the first Korean vowel. do.

In addition, whether the input vowel is a short vowel or a double vowel and a complex vowel can be easily determined depending on what is input after the 9 button or the # button. That is, when the consonant button is pressed in the situation where the button 9 or the # button is pressed once, it corresponds to a short vowel, and thus the first Korean vowel of the button 9 or the # button is determined as 'ㅡ' and 'ㅣ', respectively. Therefore, in this case, a Hangul character is synthesized by combining the '-' and '-' and the consonant button pressed behind. At this time, whether the pressed consonant is used as a back letter after the currently inputted vowel or as the first letter of another vowel following it is determined by what button is entered after the consonant button, which is widely adopted in the prior art. In this invention, even if the description is omitted, those skilled in the art can easily grasp. For example, after pressing the button 9 and pressing the 'ㅂ' button, the first Korean vowel of the button 9 is recognized as 'ㅡ' instead of 'ㅗ' to generate 'ㅡ'.

Meanwhile, when the vowel button is pressed again when the ninth button or the # button is pressed once, it corresponds to a vowel vowel and a compound vowel, and thus the first Korean vowel of the ninth button or the # button is respectively 'ㅗ' or 'TT'. Judging by. Therefore, in this case, the double vowels obtained by combining the '및' and 'TT' and the vowel buttons pressed behind are read and provided. For example, after pressing button 9, pressing the '을' button generates 'ㅘ' by recognizing the first Korean vowel of the first button as 'ㅗ' instead of 'ㅡ'.

According to another embodiment of the present invention, a Hangul input device according to another embodiment of the present invention may include a third corresponding input when consecutive input buttons corresponding to the conversion button and the first Hangul vowel input are sequentially input regardless of the order of pressing the conversion button and the input button. You can also input Korean vowels.

Accordingly, the third Korean vowel may be input by pressing a predetermined input button three times or by pressing the predetermined input button once and pressing the conversion button once. In this case, the former method of inputting a predetermined input button three times may input a plurality of Korean vowels according to the number of inputs while using the same input button, and the user may be configured to have highly related vowels arranged on the same input button. There is an advantage that the vowels arranged on the input button can be easily recognized, and the latter method using the conversion button has an advantage of reducing the number of times of button input once compared to the former method.

For example, in the case of inputting 'ㅑ', the user can input by pressing the button 3 to which 'ㅏ' is assigned three times, or pressing the button once and then pressing the convert button once. The same is true of 'ㅕ', 'ㅛ' and 'ㅠ'. Thus, by assigning 'ㅑ', 'ㅕ', 'ㅛ' and 'ㅠ' to the buttons assigned 'ㅏ', 'ㅓ', 'ㅗ' and 'TT', the user intuitively selects' ㅑ ',' It is possible to determine the buttons to which the 'ㅕ', 'ㅛ' and 'ㅠ' are assigned.

Although not shown in FIG. 3, the fourth Hangul vowel corresponding to the input of the Hangul vowel and the consonant input button 211 or the conversion button 212 is also maintained in the memory means 230. The fourth Korean vowel is a vowel that can be input by the combination of the above-described vowel input. According to an embodiment of the present invention, 'ㅒ', 'ㅖ', 'ㅘ', 'ㅙ', 'ㅚ', 'ㅝ' , 'ㅞ', 'ㅟ' and 'ㅢ' correspond to the fourth Korean vowel.

For example, one of the fourth Hangul vowels 'ㅙ' is inputted once on the button 9 assigned to the first Hangul vowel 'ㅗ' and 'ㅗ' is input when the vowel is input from the button 9 1 becomes a Korean vowel, so you only need to enter button 9 once), and the second Korean vowel 'ㅐ' can be entered as a combination of two inputs of the third button. In this case, the vowel inputs used to input 'ㅙ' are 'ㅗ' and 'ㅐ', respectively, and these two vowels are highly related to 'ㅙ' in form, so users can enter '' You can easily understand how to input 'and'. Therefore, according to the Hangul input device according to the present invention, users can easily learn a method of inputting a complex vowel derived through a plurality of button inputs as in the fourth Hangul vowel.

Similarly, in the case of 'ㅘ', the input is performed by a combination of the first input of the button 9 assigned with the first Korean vowel 'ㅗ' and the one input of the third button assigned the second Korean vowel 'ㅏ'. Can be. In case of 'ㅝ', it is input as a combination of one time input of the '#' button to which the first Korean vowel 'TT' is assigned and one time input of the sixth button to which the second Korean vowel 'ㅓ' is assigned. Can be. In the case of 'ㅞ', it is input as a combination of one input of the '#' button to which the first Korean vowel 'TT' is assigned and two inputs of the sixth button to which the second Korean vowel 'ㅔ' is assigned. Can be.

In case of 'ㅚ', 'ㅚ' is generated by inputting '9' button 1 circuit and '#' button 2 times 'ㅣ' according to the method of inputting double vowel and complex vowel. In the case of 'ㅢ', '2' is generated by inputting '9' button 2 times 'ㅡ' and '#' button 2 times 'ㅣ' according to the method of inputting double vowel and complex vowel. In addition, according to another embodiment of the present invention, since there is no vowel and compound vowel combining 'ㅗ' and 'TT' in order to input 'ㅚ', one button 9 times and one input button # once When input, 'ㅚ' can be read and displayed. In the same way, '9' can be read and displayed twice by pressing the '9' button twice and the '#' button once.

In case of 'ㅟ', input by pressing '#' button 4 times. 'ㅟ' is the only vowel where both vowels that are combined are located on a single button (the '#' button). To input 'ㅟ', input 'tw' button 1 time 'TT' and enter 2 times 'ㅣ' of same button and enter '#' button 3 times, but this is the same as input method 'ㅠ' So, accepting the only exception, press the '#' button four times to enter. Alternatively, press the '#' button once, press the convert button ('*' button) once to create 'ㅠ', and then press the '#' button again. Create

In the case of 'ㅒ', enter the input button 3 corresponding to 'ㅏ' three times (or enter the input button 3 once and enter the conversion button once) according to the method of entering 'ㅑ', Then, enter the input button # twice according to the method of entering the double vowel 'ㅣ'. Inputting the input button # twice is because the first Korean vowel is set to 'TT' and 'ㅣ' becomes the second Korean vowel when generating the vowel in the present invention.

As described above, in order to input 'ㅒ', in principle, the button input button # should be input twice, but according to another embodiment of the present invention, a double vowel in which 'ㅑ' and 'TT' are present is present. Since the input button # is input once, 'ㅒ' may be read and displayed. In other words, in case of 'ㅒ', input button 3 corresponding to 'ㅏ' three times (or input button 3 once and input conversion button once depending on how to input 'ㅑ'). Then, the input button # only needs to be input once, not twice. The user can then view the displayed screen and reduce the number of inputs.

In this way, the number of similar types of Hangul input can be reduced. The vowel vowels are 'ㅒ', 'ㅖ', 'ㅚ' and 'ㅢ'.

That is, 'ㅒ' may be input by a combination of a method of inputting 'ㅑ' and a method of inputting 'ㅣ'. Even in this case, the user can easily input 'ㅒ' due to the morphological association between 'ㅑ' and 'ㅣ' and 'ㅒ'. In addition, in order to input 'ㅒ', input the number 3 button corresponding to 'ㅏ' once and input the conversion button ('*' button) once to generate 'ㅑ', and then correspond to 'ㅣ' By inputting the '#' button once, 'ㅒ' can be generated with a total of three inputs.

4 is a flowchart illustrating a Hangul input method according to the present embodiment. Hereinafter, a method of inputting a Hangul character called 'conversion' will be described in detail with reference to FIG. 4.

'ㅂ' that constitutes the first syllable among the Hangul characters called 'conversion' is a Hangul consonant. Therefore, in step S401, the second button corresponding to the Hangul consonant 'ㅂ' is input once in the button arrangement as shown in FIG. 1. In this case, since button 2 is inputted once, the number of button inputs is determined once in step S402. 'ㅂ' corresponds to the first Hangul consonant button (step S403) and no further button input is required (step S406), so the Hangul vowel button input is received in step S407.

Next, a step for inputting a Korean vowel corresponding to 'ㅕ' among the letters 'side' will be described. There are two ways to enter the Hangul vowel 'ㅕ'. The first method is a method of converting 'ㅓ ㅔ' to 'ㅕ' by pressing the input button 6 corresponding to 'ㅓ ㅔ' three times. The second method is a method of converting 'ㅓ ㅔ' to 'ㅕ', which is a third Korean vowel, by pressing the number 6 button corresponding to 'ㅓ ㅔ' once and then pressing the conversion button * once.

In the second method, order restrictions may not be applied to the Hangul vowel button input and the conversion button input. That is, when the sixth button is pressed once and the conversion button * is pressed once, and the pressing the sixth button once after pressing the conversion button *, the same '입력' may be input.

First, the step of inputting '단계' by the first method will be described with reference to FIG. 4. In operation S407, the Korean vowel is input from the input button 6 (see FIG. 1). In step S408, the number of times of inputting the sixth button is determined. Since the sixth input button is input three times to input '를', the number of button inputs is determined three times in step S408. Therefore, in step S411, '3', which is a third Korean vowel input by the button 6, is input.

Next, the step of inputting 'ㅕ' by the second method will be described. In the same manner as in the first method, the Hangul vowel is input from the input button 6 in step S407 (step S407), and the number of times of inputting the Hangul vowel input button is determined in step S408. Since it corresponds to a combination of inputting the Korean vowel input button once and the conversion button once, the input number of the input button 6 is one time and the corresponding Korean vowel is 'ㅓ' as the first Korean vowel (steps S408 and S409). If there is an input of the conversion button (step S412), the third Hangul vowel 'ㅕ' is input in combination with the input of the Hangul vowel (step S411). Thus, the letter 'rice' is entered.

Although FIG. 4 illustrates a configuration of receiving a conversion button input after receiving a vowel button input, a third Korean vowel may be input even when a Korean vowel is input after receiving a conversion input.

In the case of inputting a Hangul character without a support, or not inputting another Hangul character, since further button input is determined as 'none' in step S413, the Hangul character input according to the present embodiment is terminated. In the present example, the letter 'side' corresponds to the case where the support is present and the letter 'circle' must be input. Therefore, the determination result in step S413 determines that the button input is 'yes'.

In step S414, it is determined whether the new button input is a Korean consonant button input or a Korean vowel button input. In the case of the Korean consonant button input, step S402 is performed. In this example, since it is a case for inputting a Korean consonant of 'b', the number of button inputs is determined in step S402. 'B' just needs to input the input button 4 once as shown in Figs. 1 and 3 (step S403). Thus, the input of the character 'side' is completed.

Next, a method of inputting a Hangul character called 'hwan' will be described. The character 'hwan' can be input in a similar way to the character 'side', but since the Korean vowel 'ㅘ' corresponds to the fourth Korean vowel as described above, only the case of inputting the vowel 'ㅘ' will be described. Description of input of consonants is omitted.

A method for inputting the 'ㅘ' will be described with reference to FIG. 4. According to the vowel input method of the present invention, a method for inputting a letter 'ㅗ' and a letter 'ㅏ' may be used to input the vowel 'ㅘ'.

First, input button 9 is pressed once to input 'ㅗ' (steps S407, S408, S409). Next, input button 3 is pressed once to input '한번' (steps S412, S413, S414, S408, S409). If button 9 is pressed once, it can be 'ㅡ' or 'ㅗ'. The display first shows 'ㅡ', and if the next input button is 'ㅏ', the 'ㅡ' and 'ㅏ' Since there is no join, we need to mark 'ㅘ'.

Through the steps as described above, when the Hangul vowel 'ㅗ' and the Hangul vowel 'ㅏ' are sequentially input, although not shown in FIG. 4, the fourth Hangul vowel 'ㅘ' is input. In addition, for the combination of each vowel button input for inputting the fourth Hangul vowel 'ㅒ', 'ㅖ', 'ㅙ', 'ㅝ', 'ㅞ', 'ㅟ' and 'ㅢ', the Hangul input described above Since it has been described in the device, the description thereof will be omitted.

As described above, the button input for inputting the Hangul character 'conversion' is summarized. Based on the input button arrangement shown in FIG. 1, i) 2 → 6 → * → 4 → 8 → 8 → 9 → 3 → 4), or ii) 2 → 6 → 6 → 6 → 4 → 8 → 8 → 9 → 3 → 4 by pressing each input button in the same order as above to input the Korean vowel or Korean corresponding to each button input. The consonant can be read from a predetermined memory means and provided to the display device.

According to the present invention, a method of inputting 'he', 'high', 'gi', 'sphere', 'gil' and 'oyster' will be described.

In the case of 'he', it is generated by one input of button 1 and one input of button 9, and 'high' is generated by one input of button 1 and two inputs of button 9. Similarly, 'gi' is generated by one input of button 1 and one input of '#' button, and 'gu' is generated by one input of button 1 and two times of '#' button. According to the character input statistics of the mobile communication terminal, 'ㅡ' and 'ㅣ' are more than twice as frequently used as 'ㅗ' and 'ㅜ', so input 'ㅡ' and 'ㅣ' with one button input. It is more efficient to make it possible, which solves the problem of the prior art Korean Patent Publication No. 2004-92653.

In the case of 'Road', it is input by the one time input of button 1 ('ㄱ'), the one time input of '#' button ('ㅣ') and the second time input of button 4 ('ㄹ'), In the case of oysters, it is input by the one time input of the first button ('ㄱ'), the second input of the '#' button ('TT'), and the second input of the fourth button ('ㄹ').

Embodiments of the invention also include computer-readable media containing program instructions for performing various computer-implemented operations. The computer readable medium may include program instructions, data files, data structures, etc. alone or in combination.

According to the present invention, 'ㅗ' and 'ㅡ' are assigned to one button, 'TT' and 'ㅣ' are assigned to another button, and when 'double' is input, '복' and 'TT' are removed. 1 Read as Hangul vowels, and when inputting other Hangul vowels, 'ㅡ' and 'ㅣ' are read as the first Hangul vowel, so frequently used 'ㅡ' and 'ㅣ' can be input by one button input. This allows you to minimize the number of button inputs for other vowel inputs.

In addition, the present invention arranges the vowel and the consonant buttons so that each Hangul character has the same correlation, so that the user can easily input the Hangul characters easily and easily, while using the minimal button for inputting the Hangul vowel.

As described above, the present invention has been described by way of limited embodiments and drawings, but the present invention is not limited to the above-described embodiments, which can be variously modified and modified by those skilled in the art to which the present invention pertains. Modifications are possible. Accordingly, the spirit of the present invention should be understood only by the claims set forth below, and all equivalent or equivalent modifications thereof will belong to the scope of the present invention.
